8700k problems

[Dustifier]

Hello, i bought myself an upgrade today. 

An 

8700k

Asus prime z370p

32 gb ram 

Kraken x42

 

I installed the components. Booted up the pc installed various drivers and then the problems started. 

 

I noticed the idle temps were high and unstable. Fluctuating between 44 and 60+ it would suddenly go up and suddenly go down in a matter of seconds. Same thing under load. When playing a game it would fluctuate between 65 and low 80 in a matter of second even when there was low usage. 

 

I tried reaplying thermal paste but to no avail. Someone recommended trying to undervolt the cpu and i used intels XTU program. I undervolted it to -0,125 and ran a 10 min stress test. The max temp would not exceed 82 degrees under 100% load, so i tought the issue was resolved. It was not. 

 

Again the idle temp was high and unstable and load temp was also high and unstable.

 

I then tried to take out the kraken x42 and put in my old kelvin t12. (silly me didnt know the kelvin t12 fit the lga 1151 socket. Had i known that i would never have bought the kraken) and after bootup the temps seemed stable at 32 degrees and didnt exceed 65 under load. I tought the issue was resolved and again it was not. After turning off the game i noticed that the temp wouldnt come all the way down.  It stayed at 52 degrees idle and with inly 2% CPU usage! 

 

Now im sitting here worried there might be something wrong with th CPU and i wonder if i should return in and buy another one.  

 

Maybe i should consider wiping the pc and do a clean windows install? I didnt have any of these problems when switching from a 4690k to the 4790k but i didnt change mobo for that and its the same chipset. Maybe old mobo drivers are conflicting the new ones? 

 

I realise a 6 core processor is going to run hotter to than the 4 core 4790k but this is just ludicrous.

Yeah, i get 80c on load with my old hyper 212x dual fan on my 8600k after OC, mabye rma your cpu?

Something wrong with the kraken it seems

That's normal. Liquid coolers dont cool their liquid back to ambient temps immediately after idle.

verify your MCE (MultiCore Enhancement) in the UEFI is set to disable

Check The clock of your 8700K. Maybe there's Motherboard software run any auto OC, like my MSI Z370 Motherboard to my 8700K. I don't touch any OC button from the 1st time I run it after finish build it, but when I see on the Motherboard utility software, it run 4.2-4.4 GHz clock with 47.0 ratio by itself, while 8700K standard clock is 3.7GHz. This bring the temp relatively much higher than I expected. I use air cooler, it was 47-51^oC on daily use, and 71^oC on 1080p max setting gaming before I lower the clock manually. After I manually lower it, the temp down to 39^oC on daily use and 53^oC on gaming with 1080p max setting.

I'm not sure if it runs that clock by MSI software or Intel Turbo Boost. Try to lower it down, and you'll see the temp will follow. That's what i did to my 8700K.

 

I use a mid-tier air cooler. I'm expecting yours should be lower than mine as you are using AIO.
